webview 加载富文本图片自适应

亲测可用

WebSettings settings =webview.getSettings();

settings.setJavaScriptCanOpenWindowsAutomatically(true);

settings.setUseWideViewPort(true);//将图片调整到适合webView的大小

settings.setLoadWithOverviewMode(true);//缩放至屏幕大小

settings.setBlockNetworkImage(false);//解决图片加载不出来的问题

settings.setAllowFileAccessFromFileURLs(true);//是否允许跨域

settings.setAllowUniversalAccessFromFileURLs(true);

1.加载富文本方法

webview.loadDataWithBaseURL(null, getHtmlData(“此处为要加载的富文本内容”), "text/html", "utf-8", null);

2.此处为js方法 

private StringgetHtmlData(String bodyHTML) {

String head ="" +

"<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no"> " +

"img{max-width: 100%; width:auto; height:auto!important;}" +

"";

    return "" + head +"" + bodyHTML +"";

}
